RESUMEN

BACKGROUND: This study aimed to evaluate and analyze the prevalence and radiological characteristics of the fabella in the Turkish population, detecting differences between genders by examining magnetic resonance imaging (MRI) images of subjects. METHODS: A total number of 504 patients aged >18 years who were admitted to the orthopedics and traumatology clinic between November 2018 and October 2020 were included in this retrospective cross-sectional study. Bilateral MRI images that were taken from each patient were randomly selected. Age, sex, laterality (right or left knee), and size of the fabella were retrieved from institutional database records. P-value<0.05 is considered statistically significant. RESULTS: A total of 504 patients were included with 213 males and 291 females. The overall prevalence of fabella was 20.63%. The mean length, thickness, and width of the fabella were 6.05 mm, 4.63 mm, and 5.92 mm, respectively, in the overall population. The fabella was significantly wider, thicker, and longer in males compared to females in the Turkish population. CONCLUSION: This study revealed similar prevalence rates of the fabella in the Turkish population with Caucasian populations and similar size of the fabella in the Asian population. When different prevalence rates and sizes of the fabella among different ethnic populations are considered, it is critical to understand the prevalence or radiological features of the fabella in Turkish subjects to avoid misinterpretation of fabella diseases.

RESUMEN

BACKGROUND: Upper extremity arterial aneurysms are not common clinical conditions. It may causes ischemic gangrene or limb losses as a result of thromboembolic events due to endothelial damage. In this study, we aimed to investigate the etiology, management, and long-term outcome. METHODS: A total of 55 upper extremity aneurysms between January 2009 and April 2018 were retrospectively investigated. The mean age was 41 ± 13 years, and the women and men were 13 (23.6%) and 42 (76.4%). The mean follow-up was 43 ± 18 months. RESULTS: The incidence of pseudoaneurysm was higher than the true aneurysm (64.5% vs. 35.5%). 30 (84%) patients who had pseudoaneurysm repaired primerely and 6 (16%) patients had patchplasty. About 58% of the true aneurysm caused by blunt trauma. 4 (21%) true brachial aneurysm patients were required emergency intervention due to distal ischemia. 16 (84.2%) patients operated using by saphenous vein graft. The primary and secondary patency was 87.5% and 93.8%. No limb or life loss occurred during follow-up. CONCLUSION: Pseudoaneurysms are more common among upper limb aneurysms and they occur mostly by iatrogenic causes. Blunt trauma can be main cause of the true aneurysm. Surgical resection of the aneurysm and interposition of saphenous vein graft provides excellent results in the long-term.

ANTECEDENTES: los aneurismas arteriales de las extremidades superiores no son condiciones clínicas frecuentes. Puede causar gangrena isquémica o pérdida de extremidades como resultado de eventos tromboembólicos por daño endotelial. En este estudio, nuestro objetivo fue investigar la etiología, el tratamiento y el resultado a largo plazo. MÉTODOS: Se investigaron retrospectivamente un total de 55 aneurismas de las extremidades superiores sometidos a reparación quirúrgica entre enero de 2009 y abril de 2018. La edad media fue de 41 ± 13 años, y las mujeres y los hombres tenían 13 (23.6%) y 42 (76,4%). El seguimiento medio fue de 43 ± 18 meses. RESULTADO: La incidencia de pseudoaneurisma fue mayor que el aneurisma verdadero (64.5% frente a 35.5%) y fue causado por un traumatismo iatrogénico. 30 (84%) de los pseudoaneurismas reparados con cualquier injerto, 6 (16%) pacientes requirieron plastia con parche. 58% del aneurisma verdadero causado por traumatismo cerrado. 4 (21%) pacientes con aneurisma braquial verdadero requirieron intervención de emergencia debido a isquemia distal. 16 (84,2%) pacientes fueron sometidos a operación de reparación de aneurisma mediante injerto de vena safena. La permeabilidad primaria y secundaria fue del 87.5% y 93.8%. No se produjeron pérdidas de miembros ni de la vida durante el seguimiento. CONCLUSIÓN: Los pseudoaneurismas son más comunes entre los aneurismas de miembros superiores y ocurren principalmente por causas iatrogénicas. El traumatismo cerrado es la principal causa del verdadero aneurisma. La resección quirúrgica del aneurisma y la interposición con injerto de vena safena proporciona excelentes resultados a largo plazo.

RESUMEN

OBJECTIVES: The primary aims of the study to evaluate the efficacy of carotid screening tests to identify asymptomatic carotid artery stenosis among high-risk patients and early prevention of stroke. BACKGROUND: The estimated prevalence of asymptomatic severe carotid stenosis (≥70%) in the general adult population ranges up to 3.1%. However, the prevalence is higher in comorbid individuals. This makes it important to perform screening testing for early diagnosis and treatment in predetermined high-risk patients. MATERIAL AND METHODS: In this prospective study, 3000 selected patients screened during March 2017 and September 2018 at the most populated family health center. Participants selected among registered individuals who have at least one of the risk factors such as hypertension, hyperlipidemia, diabetes mellitus, obesity, and smoking. All the participants were asymptomatic and above the age of 55. Bilateral carotid artery screening performed by Duplex Ultrasonography (DUSG) at the first call and one year later. Patients with severe carotid and/or coronary artery stenosis treated by surgical revascularization or stent implantation in the light of the latest guidelines. CONCLUSION: Carotid screening among high-risk asymptomatic individuals is of great importance to identify severe carotid artery as well as coronary artery stenosis. Patient education during screening may play a crucial role in preventing the disease.

RESUMEN

BACKGROUND: Charcot's neuroarthropathy (CN) treatment is still controversial, and the results are controversial. Owing to patient comorbidities, surgical intervention carries a high risk of complications. Thus, foreseeing the possible results of planned treatment is crucial. We retrospectively evaluated the Charcot Reconstruction Preoperative Prognostic Score (CRPPS) in patients with surgically treated CN. METHODS: Twenty-two feet of 20 patients were included in the study. Two groups were formed according to their CRPPS. Twelve patients with values less than 4 were defined as group A, and eight patients with values of 4 or greater were defined as group B. Mean follow-up was 61 months (range, 5-131 months). Groups were compared according to American Orthopaedic Foot and Ankle Society (AOFAS) scores, Foot and Ankle Disability Index (FADI) scores, and complication rates. RESULTS: Group A and B mean AOFAS scores were 76.83 (range, 71-85) and 70.5 (range, 20-85), respectively. All of the patients were improved according to AOFAS and FADI scores, but no correlation was found with the CRPPS. None of the group A patients required additional intervention, but five patients in group B underwent revision surgery. No amputations were performed. CONCLUSIONS: The CRPPS is focused on feasibility. The data needed to fill the scoring system is easily obtainable from medical records even retrospectively, and the score is helpful to predict a patient's outcome after CN-related surgery. Herein, CRPPS values of 4 or greater were related to high complication rates and lower functional outcomes.

RESUMEN

Chondroblastoma located in the talus is a rare incidence, and due to the weightbearing duty of the talus, the results of local excision may not be favorable. While the volume of the tumor increases, more sophisticated techniques may be undertaken. Cell-free matrix application for extensive osteochondral defects is gaining popularity for its structural support when it is used with microfracture and autograft application. In this case report, we present a patient with 13 × 20 × 8mm-sized chondroblastoma located in the talus. After evaluation of the mass, we performed curettage, iliac crest autograft application, and augmentation with cell-free matrix. After uneventful clinical follow up, we present our patient's postoperative second year magnetic resonance imaging and functional status.

RESUMEN

INTRODUCTION AND OBJECTIVE: Total hip arthroplasty with rectangular femoral component and transverse osteotomy for patients with Crowe type 3 or 4 dysplasia yields successful results with varying radiological findings. This study aims to investigate the surgery and patient related factors associated with successful clinical and radiological results. PATIENTS AND METHODS: Fifty hips of 41 patients were retrospectively examined. Length and percentage of the stem passing the osteotomy level and canal fill ratio were measured. Radiological findings such as radiolucent lines (RL) around the stem, hypertrophic callus or an identifiable osteotomy line on X-ray images were assessed. All clinical and radiological results were analyzed for any significant association. RESULTS: Mean stem length and percentage passing the osteotomy level were 6.4 cm (± 0.7) and 51% (± 6). Presence of an identifiable osteotomy line was positively associated with the increasing length of the stem passing the osteotomy level and with a lower HHS (p < 0.05). RL around the stem were associated with a lesser reduction in VAS score (p < 0.05). CONCLUSION: Rectangular femoral stem conveniently accommodate the proximal femur in severely dysplastic hips. An upper limit for the femoral stem exists to obtain better bony union and higher HHS. RL around the stem are clinically relevant and is associated with a worse VAS score at the latest follow-up.

RESUMEN

BACKGROUND: Total hip arthroplasty (THA) involving shortening osteotomy for patients with Crowe type 3 or 4 dysplasia is a challenging surgical procedure. This study aims to demonstrate that rectangular femoral component use in anatomical reconstructions with THA and transverse shortening osteotomy yields successful results without the use of bone graft or any fixation material at the osteotomy site. METHODS: Fifty hips from 41 patients were identified retrospectively as per study objectives. All patients were evaluated using the Harris Hip Score and Visual Analog Scale for pain. Complications were reported. Radiological evaluation criteria were then evaluated, including leg length discrepancy, degree of trochanter caudalization and stem subsidence, radiolucent and radiodense lines for both components and bone atrophy or hypertrophy around the stem according to Gruen zones, and the canal fill ratio of the stem. RESULTS: Postoperative Harris Hip Score was excellent for 68% of patients. No patient had poor results. Complication rate was 32%. One patient had nonunion (2%). The mean postoperative leg length discrepancy was 0.8(±0.6) cm. No patient had a subsidence of more than 5 mm. Radiolucent and radiodense lines were present in up to 34% of patients, and bone atrophy was present in the proximal femur in up to 96% of patients. No patient had osteolysis or loosening in neither component. CONCLUSION: Successful clinical and radiological results can be obtained from Crowe type 3 and 4 dysplastic hips operated on with THA using a rectangular femoral component and transverse shortening osteotomy technique. The use of graft or any fixation material at the osteotomy site is not mandatory.

RESUMEN

OBJECTIVE: This study aimed to evaluate whether a history of a pelvic osteotomy or proximal femoral osteotomy compromises the outcomes of total hip arthroplasty in patients with dysplastic coxarthrosis. METHODS: The results of total hip arthroplasty in 240 hips of 172 patients without previous pelvic osteotomy or proximal femoral osteotomy were compared to 118 hips of 88 patients with a previous pelvic osteotomy or proximal femoral osteotomy (osteotomy group). Technical difficulties and rates of complications during surgery, operative time, estimated blood loss, rates of postoperative complications, and pre- and postoperative Harris Hip Scores and visual analog scale pain scores were compared between the two groups. RESULTS: In the osteotomy, the rate of complications was higher and the operative time was longer. The estimated blood loss was also higher, and the latest follow-up Harris Hip Scores and visual analog scale pain scores were worse in this group. Total hip arthroplasty was more demanding and the revision rate was higher in the osteotomy group (six vs four revisions). CONCLUSION: Our data showed that a previous history of pelvic osteotomy or proximal femoral osteotomy compromised the clinical outcomes of subsequent total hip arthroplasty and is related to an increased rate of complications, prolonged operative time, and increased amount of blood loss. LEVEL OF EVIDENCE: Level III, Therapeutic Study.

RESUMEN

OBJECTIVE: The aim of this study was to determine the effects of age and body mass index (BMI) on the functional outcomes, satisfaction rates, and recovery time after open debridement and reattachment surgery in non-athletic patients with insertional Achilles tendinopathy (IAT). METHODS: In this retrospective study, 33 non-athletic patients (34 ankles) in whom open debridement and reattachment surgery was performed for IAT from 2006 to 2016 were included. Change in pain intensity was assessed using a Visual Analogue Scale (VAS) preoperatively and at the final follow-up. Functional assessment was done by preoperative and postoperative American Orthopaedics Foot and Ankle Score (AOFAS) and final follow-up Victorian Institute of Sport Tendon Study Group-Achilles Tendinopathy score (VISA-A). Patient satisfaction was evaluated by Roles - Maudsley score (RMS). The recovery time was defined as the time interval from the first appearance to postoperative relief of symptoms and recording. In addition, the recurrent Haglund's deformity was determined by postoperative control radiographs. RESULTS: The mean age at the time of the operation was 51.19 years. The mean follow-up was 61.75±8.49 months. According to BMI, 5 patients were determined as morbid obese, 19 as obese, 3 as overweight, and 6 as normal. The mean VAS score significantly decreased from 8.5 preoperatively to 1.3 postoperatively (p<0.001). The mean AOFAS score significantly improved from 55.8 preoperatively to 92 postoperatively (p<0.001). Postoperative VISA-A score was 86% (range=32%-100%). According to RMS, 22 patients reported the result as excellent, 8 as good, 2 as fair, and 1 as poor. The mean recovery time was 11.8 (range=2-60) months, but one patient did not reach a symptom free status and thus was not included in the recovery time analysis. Postoperative control radiographs revealed signs of recurrence deformity in four patients. Recovery time showed a negative correlation with the age of the patients (r=-0.65). Postoperative scores and BMI showed no significant correlations with the recovery time on the basis of Spearman's rho test (p=0.196). CONCLUSION: The results of this study have shown that open debridement and reattachment surgery may be an effective surgical method in relieving pain and improving functional status with high satisfaction rate and acceptable recovery time in the management of non-athletic patients with IAT. LEVEL OF EVIDENCE: Level IV, Therapeutic study.

RESUMEN

OBJECTIVE: This prospective study aimed to evaluate the changes in the sagittal alignment after total hip arthroplasty (THA) in patients with hip osteoarthritis (OA) secondary to Crowe type-IV developmental dysplasia of the hip (DDH) and whether THA would contribute to the relief of low-back pain (LBP). METHODS: A total of 27 patients (2 men and 25 women) with bilateral hip OA secondary to Crowe type-IV DDH were enrolled in this study. Their mean age at the time of surgery was 40,36±12,35. All patients underwent simultaneous, bilateral THA between January 2015 and December 2016. Clinical assessment included Oswestry disability index (ODI) score and Harris hip score (HHS), and pelvic incidence (PI), sacral slope (SS), lumbar lordosis (LL), and pelvic tilt (PT) were measured from radiographs. RESULTS: Preoperatively, all the patients had hip and low-back pain. Preoperative and final follow-up ODI scores were 48.3 and 3.9 (p=0.000), respectively. HHS changed from 43.54 to 92.68 (p=0.000). PT and PI significantly changed from -20.4°±20.4° to 3.2°±16.7° (p=0.001) and from 26.6°±35.1° to 47.4°±17.9° (p=0.001), respectively. There were no significant differences regarding the SS and LL measurements. Age or limb-length discrepancy was not significantly associated with the spinopelvic alignment measurements. CONCLUSION: Restoring the function of the hip with THA is shown to improve hip-associated LBP, but the accompanying hyperlordosis does not change. THA in patients with bilateral Crowe type-IV hips relieves hip pain as well as associated LBP. Hyperlordosis of the lumbar vertebra does not change after surgery, but PI and PT changes are observed; this improvement might have a role in the relief of LBP. LEVEL OF EVIDENCE: Level IV, Therapeutic study.

RESUMEN

BACKGROUND: Total hip arthroplasty in severe dysplasia is challenging due to diminished periacetabular bone stock and the highly placed femoral head. Although anatomical reconstruction of the hip, with required interventions such as subtrochanteric osteotomy and graft usage, is the main aim of the procedure, good long-term clinical outcomes of the high hip center technique have also been reported. Information regarding the effect of hip center placement on gait characteristics is limited; therefore, the aim of this study is to analyze the differences in gait parameters between the high hip center technique and anatomical reconstruction of the hip. METHODS: Twenty patients (40 hips) with bilateral Crowe type III-IV developmental dysplasia of the hip who underwent bilateral total hip arthroplasty and completed at least 2 years of follow-up were included. Group 1 comprised 10 patients (20 hips) who underwent anatomical hip center reconstruction, while group 2 comprised 10 patients (20 hips) who underwent high hip center reconstruction. The gait characteristics of patients were examined through markers placed in certain anatomical regions, the cameras placed around, and the force plates embedded in the walking platform. RESULTS: There was no significant difference in the gait characteristics according to the location of the hip rotation center. The mean temporospatial, kinematic, and kinetic values were similar between the groups. The most prominent difference was in the peak dynamic hip extension, which was lower in group 2 (-9.71° ± 7.46°) compared to group 1 (-6.80° ± 11.44°), although it was not statistically significant (P = .09). CONCLUSION: The bilateral high hip center technique can provide similar gait characteristics as anatomical reconstruction and may be preferred in particularly difficult cases based on the surgeon's decision.

RESUMEN

OBJECTIVE: The aim of this study was to assess the effectiveness of microfracture and cell free hyaluronic acid (HA) based scaffold combination in the treatment of talus osteochondral defects (OCD). METHODS: This study retrospectively evaluated the clinical results of the 20 patients (14 males and 6 females, mean age at the time of surgery: 32.9 years (range: 16-52 years)) who were treated with MFx and cell-free HA-based scaffold combination for talus OCD smaller than 1.5 cm2 and deeper than 7 mm. Results were evaluated with AOFAS and VAS scores. Also, patients' satisfaction was questioned. RESULTS: Patients were evaluated after an average follow-up of 20.3 months. Intraoperative measurements showed that mean depth of the lesions were 10.4 ± 1.9 mm after debridement. The mean preoperative AOFAS score was 57.45 ± 9.37, which increased to 92.45 ± 8.4 postoperatively (p < 0.05). VAS score was improved from 7.05 ± 2.45 to 1.65 ± 2.20 postoperatively (p < 0.05). CONCLUSION: MFx and cell-free HA-based scaffold combination appear to be a safe and efficient technique that provide good clinical outcomes for lesions deeper than 7 mm. LEVEL OF EVIDENCE: Level IV, Therapeutic Study.

RESUMEN

BACKGROUND: The optimal rehabilitation program for patients with post-total hip arthroplasty (THA) after developmental dysplasia of the hip (DDH) remains unclear. OBJECTIVE: The aim of the present study was to evaluate the clinical outcomes, to define a postoperative rehabilitation program, and to report the complication rate of THA in patients with DDH. METHODS: DDH hips (n= 89) were recruited. The transverse proximal femoral shortening osteotomy was applied to all patients. The rehabilitation program was performed on the first day immediately after operation to the 6th week. Pain was assessed via Visual Analogue Scale, and the function was evaluated by the Harris Hip Score at the end of the 3rd month and the first year. The weakness of hip abduction was assessed via the Trendelenburg test before the operation and at one year. RESULTS: Statistically significant improvements were seen for pain (p< 0.001) and function (p< 0.001) in the third month. This improvement continued for pain from three months to one year (p< 0.001). However, the function did not increase from month three to one year (p= 0.47). The Trendelenburg test was positive in all cases in the first assessment; it decreased to 24.7% at one year. The complication rate was 11.23%. CONCLUSIONS: The pain and function of patients who performed exercise following THA due to DDH might improve, especially in the first three months.

RESUMEN

Hemophilia is a disorder of blood coagulation with X-linked recessive inheritance. It is characterized by uncontrollable hemorrhage, and 80% of these occur intraarticularly. With recurrent hemarthrosis, recurrent synovitis occurs, which eventually leads to the formation of articular contractures. The key to the prevention of hemophilic joint complications is successful prevention of bleeding and management of the initial hemarthrosis. However, after the development of a rigid contracture, surgical correction remains the only method to correct the deformity. Achilles tendon lengthening, synovectomy, anterior osteophyte resection, corrective osteotomies, external fixators, or arthrodesis should be considered as surgical options. In the present report, we describe our experience using hybrid-type external fixators to manage bilateral neglected rigid equinus contractures in a hemophilic patient, with 78 months of follow-up data.

RESUMEN

BACKGROUND: We argue that 1-stage bilaterally total hip arthroplasty (THA) could be acceptable in bilateral coxarthrosis because of high-riding developmental dysplasia of the hip (DDH). METHODS: Sixty-nine cases (51 patients) of high-riding DDH in patients who underwent THA from 2010 to 2013 were reviewed. Patients were divided into 2 groups: unilateral (group 1) and 1-stage bilateral surgery (group 2). The clinical measurements were the visual analog scale and Harris Hip Score. RESULTS: The average follow-up was 37.3 months for group 1 and 38.8 months for group 2. The hospital stay time was 5.2 days in group 1 and 6.2 days in group 2 (P = .334). The mean Harris Hip Score and visual analog scale score were improved significantly after surgery for both groups, and there was no statistically significant difference (P = .988). There was no difference between groups 1 and 2 in terms of complications (P = .137). CONCLUSION: Our data confirm that 1-stage bilateral transverse osteotomy with THA is an effective method as unilateral and it does not increase the length of patients' hospital stays and features a low risk of postoperative complications in the treatment of patients with high-riding DDH.

RESUMEN

OBJECTIVES: High tibial osteotomy (HTO) is a well-established procedure for the treatment of medial knee osteoarthritis originating from malalignment of the lower extremity. The current study was designed to evaluate the clinical and radiographic results of closed-wedge HTO for the treatment of medial knee osteoarthritis and to reveal factors affecting the outcome. METHODS: A retrospective study was conducted with 138 patients who were operated on for medial knee osteoarthritis between 2000 and 2007 using closed-wedge HTO. Preoperative and follow-up physical examination findings, body mass index (BMI) values, and Hospital for Special Surgery (HSS) and Lysholm knee scores were reviewed. Radiographic evaluation included measurement of the mechanical axis preoperatively and the most recent follow-up orthoroentgenograms. The follow-up knee scores were evaluated according to preoperative mechanical axis, obesity, age, follow-up period, and gender of the patient. The mechanical axis measurement was assessed based on obesity, age, and follow-up period. RESULTS: The mean preoperative and latest follow-up mechanical axis was 4.92o±4.24o varus and 3.43o±3.74o valgus, respectively (p=0.0001). Improvement in the Lysholm (p=0.0001) and HSS (p=0.0001) knee scores was significant. The preoperative mechanical axis, obesity, follow-up period, and gender had no negative effect on the follow-up knee scores, whereas a preoperative age over 50 years had a negative effect on the follow-up knee score. Obesity and the length of the postoperative follow-up period did not have a negative effect on the postoperative mechanical axis, whereas a preoperative age over 50 had a negative effect on the postoperative mechanical axis. CONCLUSION: The results of this study suggest that medial knee osteoarthritis may be treated successfully with closed-wedge HTO. The analysis indicated that factors such as obesity, the degree of preoperative deformity, and gender do not adversely affect the success of treatment. However, a preoperative age over 50 adversely affected the outcome.

RESUMEN

Tibiofemoral instability is a common complication after total knee arthroplasty (TKA), accounting for up to 22% of all revision procedures. Instability is the second most common cause of revision in the first 5 years after primary TKA. In this study, 13 knees with tibiofemoral instability after TKA were identified among 693 consecutive primary TKA procedures. Patient demographics, body mass index, clinical symptoms, previous deformity, previous knee surgery, complications, interval between index TKA and first tibiofemoral instability, causes of instability, and interval between index TKA and revision TKA were retrospectively reviewed. Clinical outcomes were assessed with the Lysholm Knee Scoring Scale. All patients were women, and mean body mass index was 37.7 kg/m2 (range, 27.2-52.6 kg/m2). Mean interval between index TKA and first tibiofemoral instability was 23.4 months (range, 9-45 months), and mean interval between index TKA and revision TKA was 25.6 months (range, 14-48 months). All patients had posterior cruciate ligament-retaining implants. Of the 13 knees, 11 had flexion instability and 2 had global instability. In all patients, instability was caused by incompetence of the posterior cruciate ligament; additionally, 1 patient had undersized and malpositioned implants. In 4 knees, the polyethylene insert was broken as well. All patients underwent revision TKA. Lysholm Knee Scoring Scale score had improved from a mean of 35.8 (range, 30-46) to a mean of 68.3 (range, 66-76). All patients included in this study were female and obese. The main cause of instability was secondary posterior cruciate ligament rupture and incompetence. The use of posterior-stabilized implants for primary TKA may prevent secondary instability in obese patients. [Orthopedics. 2017; 40(5):e812-e819.].

RESUMEN

OBJECTIVE: Idiopathic flexible pes planus (IFPP) is a common foot problem in adolescents and young adults. Hypothesis for the present study was that combination of procedures for IFPP can achieve results in adolescents and young adults that are as good as those seen in adult-acquired pes planovalgus (AAPP) treatment in adults. METHODS: A total of 21 feet of 18 patients (10 boys, 8 girls) with mean age of 15.6 years underwent surgical reconstruction for flatfoot deformity. Symptomatic patients who had been unresponsive to conservative treatment were included in study group. Mean follow-up time was 39.2 months. American Orthopedic Foot and Ankle Society (AOFAS) scores were calculated for all patients, and based on final results, all families were asked whether or not they would elect to have the surgery again in same circumstances. RESULTS: All procedures were performed by the same surgeon: lateral column calcaneal lengthening osteotomy on 21 feet; percutaneous lengthening or gastrocnemius recession for Achilles tendon on 21 feet; medializing calcaneal osteotomy on 15 feet; flexor digitorum longus tendon transfer on 15 feet; medial cuneiform opening wedge osteotomy on 5 feet, spring ligament plication on 3 feet, and accessory navicular bone excision on 2 feet. Preoperative mean AOFAS score increased significantly from 56.76 to 95.29. All parents stated that they were satisfied with surgery results and would choose to have the same surgery performed again. CONCLUSION: Soft tissue and bony procedures used for reconstruction of AAPP can be used safely for IFPP in adolescents and young adults. LEVEL OF CLINICAL EVIDENCE: Level IV, Therapeutic study.

RESUMEN

OBJECTIVE: A knee fusion is associated with considerable restrictions, including the inability to sit properly, use public transportation, and climb stairs. The purpose of this study is to report and discuss our cases of spontaneous ankylosed knees which were taken down and underwent total knee arthroplasty (TKA). METHODS: Six patients who experienced spontaneous ankylosis of the knee undergoing conversion to TKA between 2003-2012 were enrolled retrospectively in this study. The etiology was childhood pyogenic arthritis in 2 patients, intraarticular fractures in 2, gunshot in 1, and juvenile rheumatoid arthritis in 1. The clinical data were recorded with the use of the Hospital for Special Surgery (HSS) knee rating system, Western Ontario and McMaster Questionnaire (WOMAC), and Visual Analog Scale (VAS), preoperatively and postoperatively at final follow-up. RESULTS: The average follow-up time was 86 months (range: 22-126 months). At the final follow-up, the average range of active flexion was 85° (range: 75-95°). Postoperative average HSS knee rating system was improved from 19.5 (range: 18-22) to 57.49 (range: 46-80), WOMAC was improved from 39.75 (range: 36.4-43) to 62.41 (range: 50.8-74.5). VAS was improved from 9.5 (range: 7-9) to 2.8 (range: 2-4). A pyogenic infection developed in 2 patients; 1 was managed by debridement, and 1 was managed by arthrodesis 2 years later. CONCLUSION: The ability to walk and sit in a normal fashion is of great importance for patients. With good preoperative planning and careful handling, gratifying results are possible with TKA.
